    Improved training materials have been developed by CAWST http://www.cawst.org while online material is available via biosandfilter.org. CAWST organizes trainings and is probably happy to share training materials they have developed with all who build filters. However, they ask that at least one person from your organization participates in the training that CAWST offer. Preferably this person should have a background in water projects or household water treatment, and can then act as your in-house expert on the technology.
